SO445120

The SO445120 is designed as phase angle controller with output of 100 to 280VAC 50A and supply of 8 to 30V and analog input of 0 to 5V.

SO445120 has eight features. (1)SSR based phase angle controller with analog control to adjust power on resistive loads (linear power law response). (2)SO4 current range : 35 to 125A. (3)Overvoltage protection by varistor. (4)Main frequency range : 40 to 70Hz with self adaptation. (5)8 to 30V supply voltage and Green LED visualization on the input. (6)0 to 5V analog input voltage. (7)Designed in compliance with EN60947-4-3 (IEC947-4-3) and EN60950/ VDE0805 (reinforced insulation). (8)IP20 protection by flaps on terminals. That are all the main features.

Some SO445120 control characteristics are concluded into several points as follow. (1)Its control voltage would be min 8V and max 30V. (2)Its supply current would be max 9mA. (3)Its max reverse supply voltage would be max 30V. (4)Its analog voltage range would be min 0V and typ 5V and max 30V. (5)Its analog input current would be max 300uA.
